MILLING-MACHINE AND THE LIKE.

To all whom it may concern:

Be it known that I, LEO S. WHITEHEAD, a citizen of the United States,residing at Wheeling, in the county of Ohio and State of WVest Virginia,have invented new and useful Improvements in Milling-Machines and theLike, of which the following is a specification.

The present invention has reference to improvements in milling machinesand the like, and it comprehends, broadly, the production of a machineof that general class having a materially increased. capacity or rangeof work, this being eifected by the provision of a specially constructedsaddle with which a series of work supports of different types areadapted for interchangeable engagement, the arrangement being such thatthe table best suited for the character of the particular Work may bereadily connected to the saddle, and adjusted relative to the same, soas to require no subsequent resetting of the work.

A structural embodiment of the invention is illustrated in theaccompanying drawing, wherein:

Figure 1 is a side elevation of the complete machine. Fig. 2 is a detailperspective view of the improved saddle. Fig. 3 is a similar view of thetable shown in Fig. 1. Figs. 41 and 5 are perspective views of differentforms of tables. Fig. 6 is a transverse sectional View of the bed andsaddle, the latter having engaged therewith the table shown in Fig. 5.

Reference being had to said drawing, and to the characters markedthereon, A indicates in a general manner the adjustable bed of amilling, shaping or similar machine, B the standard with which the bedis connected, and C the cutting mechanism mounted upon the standard andoverhanging bed A. These elements are, in the main, of con ventionaltype, and hence require neither detailed illustration nor extendeddescription.

Upon the upper face of the afore-mentioned bed A, there is adjustablymounted the saddle 5, in the particular construction of which theinvention primarily resides. This element is designed to support thethree work tables 6, 7 and 8, shown, respectively, in Figs. 3, 4 and 5,these tables being of different types and being adapted forinterchangeable employment to suit the character or requirements of theparticular work.

The saddle, therefore, is so constructed as to admit of the attachmentof any one of these tables thereto, the tables being, in turn, adaptedfor adjustment upon said saddle and for retention in adjusted position.The provision of means for centering the tables during their adjustmentis also necessary, as will be apparent. In the construction shown inFig. 2, which is at present considered most advantageous, the saddle hasa flat platelike body 9 provided at its front end with a dependingflange 10 arranged at right angles thereto. The upper face of theafore-mentioned body portion 9 has formed therein a transverse groove 11and a longitudinal groove 12, these grooves bisecting each other as wellas the corresponding side and end edges of said body, their bottomsbeing substantially flush with the upper edge wall of flange 10. Theyare designed to receive longitudinal tongues or ribs 13 and 11 formed,respectively, upon the under faces of the tables 7 and 8, whereby saidtables are guided during adjustment, as hereinafter more fullyexplained. A similar construction is also provided for insuring thecorrect sliding adjustment of the saddle, the under face of which latteris formed with a longitudinal tongue 15 received in a longitudinalgroove 16 formed in the upper face of the bed A. The tongues and groovesabove referred to may have any suitable conformation. As regards thetables themselves, it may be stated that two are preferably rectangularin shape, and the third circular, one of the two rectangular tables,namely, the table 7 being arranged for adjustment transversely of thebed, and the other rectangular table 8 for longitudinal adjustment. Anyone of these tables may be used, according to the particular characterof the work, as will be understood, and since the dimensions of all ofthe tables are considerably greater than those of the bed, the range ofthe work is proportionately increased, such increase being independentof the range of adjustment of the saddle upon the bed, and of the latteritself. Thus it will be seen that all parts of the work maybe treatedwithout necessitating any re-setting, and the dimensions of the work orobject may be much-greater than those of the saddle. As regards thecircular table 6, a carrier therefor is provided in the nature of avertical bearing sleeve 17 formed upon flange 10, the bore of saidsleeve receiving a depending axial pin or stud 18 connected to the saidtable. This sleeve is also designed to receive a similar pin or stud 19formed midway between the ends of the rib 14: on table 8. WVith thesleeve there is associated a bolt 20 threaded in the lower portion ofthe bore thereof and provided with an operating handle 21, the upper endof said bolt contacting with the lower ends of the pins or studs 18 and19.

Means are provided, as already stated, for retaining the tables inadjusted position. Such means may, as illustrated, advantageouslycomprise clamping bolts 22 movable through the perforations in a seriesof lugs 23 which project laterally from the side edges of the saddlebody 9. The heads of these bolts are designed for reception in pairs ofT-grooves 24 formed in the under faces of the tables. These grooves, inthe case of the two rectangular tables 7 and 8, are arrangedlongitudinally and adjacent the side edges thereof; in table 6, saidgrooves are in the form of concentric circles, the bolts being turned inone position to permit their insertion thereinto, and subsequentlyturned at right angles to such position to effect their retention. Attheir lower ends, the bolts carry nuts 25 which may be tightened againstthe under faces of lugs 23.

From the foregoing, it will be apparent that after the proper table hasbeen selected and connected to the saddle, the latterand the bed may beadjusted, and as the milling or other operation is continued, theposition of the table itself may be varied periodically withoutrequiring any resetting of the work. Thus it is shown that an extremelywide range of adjustment is insured, and the capacity of the machine, ineffect, increased. Where the table is mounted in the bearing sleeve, asis the case with the tables 6 and 8, it may be readily raised above thesaddle, by turning the handle 21 in the proper direction, after which itmay be adjusted.

In connection with the adjustment of the saddle, it may be stated thatthe provision of retaining devices is contemplated, such devices beingpreferably similar to those associated with the tables and comprisingbolts 26 having T-shaped heads which are received in correspondinglyshaped longitudinal grooves 27 formed in the upper face of the bed A.The threaded upper ends of these bolts project into countersunk recesses28 in the saddle and carry tightening nuts 29, as shown in Fig. 6.

I claim as my invention:

1. In a machine of the class described, the combination of a bed; asaddle adjustably mounted on said bed and constituting a companionelement thereto, one of said ele ments being provided with a groove, andthe other with a tongue slidably fitting in said groove; means forretaining said saddle in adjusted position on said bed; awork-supporting table adjustably mounted on said saddle and providedwith a pair of grooves; and a pair of bolts carried by said saddle andhaving their heads fitted in the grooves in said table for retaining thelatter in adjusted position.

2. In a machine of the class described, the combination of a bed havinga flat upper face; a saddle adjustably mounted on said bed and having aflat under face resting on the first mentioned face, said bed and saddleconstituting companion elements, one of which is provided with alongitudinal groove, and the other with a longitudinal tongue slidablyfitted therein; means for retaining said saddle in adjusted position onsaid bed; a work-supporting table adjustably mounted on said saddle andprovided with a pair of grooves; perforated lugs carried by said saddleat opposite sides thereof and disposed directly beneath the grooves insaid table; and clamping bolts movable through the perforations in saidlugs and provided with heads received in said table grooves.

3. In a machine of the class described, the combination of a bed; asaddle mounted thereon; a work-supporting table carried by the saddleand mounted upon the same, said saddle and table constituting companionelements; means carried by one of said elements and arranged forengagement with the other element to retain said table in position uponsaid saddle; and means for elevating said table above said saddle.

at. In a machine of the class described, the combination of a bed; asaddle mounted thereon and provided with a bearing sleeve; a wor-supporting table provided with a pin engaged in said sleeve, said tableand saddle constituting companion elements; means carried by one of saidelements, to retain said table in position upon said saddle; and avertically-movable member located in said sleeve and engaged with saidpin, for elevating said table above said saddle.
